Product Feature
A soft start-up valve is used to input compressed air into the pneumatic system slowly and has the effect of safety and protection. Air intake is connected with the input P of the Soft start-up valve. If the coil is energized, the 3/2 way valve opens. At this time, a little air comes to output A through the throttle valve, which increases the pressure of the system gradually; when the output pressure is equal to half of the input pressure, the Soft start-up valve completely opens and the flow at this time reaches the highest value of itself. When the coil is de-energized, air intake P closes, the air returns to the R orifice through the reflux valve and is quickly exhausted. The pressure of the system falls to zero, which protects the whole system.

Attention
Manually adjust the “+” and “-” throttle screw at the bottom of the soft start-up valve as per the requirement of start speed. It shall go slowly, otherwise sudden acting of the product or system shall be caused with a heavy impact.
